STUMP-BURNER.

Specification of Letters Patent.

VPatented Sept. 5, 1911.

Application filed January 4, 1911. Serial No. 600,696.

To all who/m 'it may concern:

.lle it known that I, FRANK P. RAND, a

eitizen of the United States, and a resident ol Spokane, in the county of Spokane and State of VaShington, have invented certain linproi'eineiits in Stump-Burners, of which the following'is a specification.

My invention is an iinlnoved device for burning` the bodies and roots of stumps, both. dry 'and green.

The eoustruotioii and manner using;r thei'levice are as hereinafter described, aud illustrated in the areonipanying drawing, in "whichW 4 Figure'l is a perspective View of i'ny inrention. Fig. 2 is a longitudinal section' oit the same. Fign is a plan 'View of the inner end of the device. F 4l is a perspective view ot the perforated partition or guard arranged in the tulni-lar body of the doiv'iee.

lieferiii'ig particularly to Figs. and 2 of? thoidiaiving, the niuueal l indicates a V.tumiel-shaped.oil reservoir and feeder, 2

an elongated tubular conductor' for the oil, 2? 'a' perforated block or partition arranged in the coi'idurtor', llun asbestos wick, and i a. wire guard arranged over the inner end o't` the dosiee, said guard serving to 'prevent 'Contact ot lire coals or other material with the v.portion of 'the asbestos wiel( lying exposed on the part 2a.

"lhe liquid fuel en'iploycd is petroleum or kerosene, and the saine .is ronveyoiil into the tubular ri'niduetor 2 'by the funnel-,shaped tunis; or reservoir l which is provided with a. Idotar-'liable nozzle l adapted for .insertion in the upturued outer end of the tube 2. The nozzle is screwed to the tank l. and has a eii'i'ular flange or collar. The discharge ond of the nozzle l. is rut away upon a slant or angle of about and the nozzle is'of suoli diameter that. it tits Very loosely into tho upturncd end oi the ronductor 2, the space lh'thus formed serving as a passage ivliiih permits the oulraiire o1 air to supply tho fvaruuni above the `oil in the reservoir. ln4 order to prevent the oil flowing` too rapidly, or rather disi'lia-i'gring attho inner end too freely, a guard or partition in the :toi-ln ot' afhlurlc 3 having a. `loniriitudinal perforation arranged in the tube 2 a. short distance troni ,its discharge end. Thus the block not only servys to hinder the too rapid disehargeof oil, but it servos also as a stop for the asbestos Wick It which 1s inserted and held in the discharge end of the tube. The latter is extended on vthe lower side, or, in other words, cut away on the upper side which is also ineised as shown in Fig. 3, `to

forni a V-sliaped opening at. 6, the saine 30,

extending back an inch orthereabout in the body of the tube. This leaves a. considerable portion of the Wick 4 exposed and also. leaves a free space for the llame, while the lower side or extended portion 2a serves as 65 a support for the wick and also for att-aehnient of the guard 5, which is so arranged as to project. above and over the outer end of the wick. The yguard is formed of Wire which is coiled at its middle about the body of the tube 2 and the ends ot the same are 'fastened to the end 2 ot said tube, the intervening portions projecting upward as showin. The oiite. end 2 of the tube is vproifided with. tee which. aid in .supportH ing; the device in iiforling position in soine situations.

ln usine' the device, it is preferable to attack a large root of a stninp ratherthan the body thereo't'. root adjacent to the stump, or just below the `round surface, and the end 21 of the device heretofore described is inserted in the hole. and then, the Wick being ignited, the

A hole is bored in the reservoir l is placed on. the upturned end `base ot' the stump past the middle or heart ot the saine, and also `to bore a second hole troni above, at an angle of say 450 to the First one, so that thetwo will coniuiunirate. The burner is :then to lbe inserted in the lower hole, and the blaze will, soon convert. the adjacent portions into llive coals, the smoke in suoli lcase escaping mainly by the upper hole. rThus the body o f the stump will in general be convert-ed into charioal without being burned to ashes, vwhich is ort cou-rse a preferable result.

A Igreen stump `cannot be burned successfully -troni the outside lby means of an 01'- dinary lire. but by use oi my 'invention even a. green stump will burn well by'attacking it in the inanner above described.

It will be understood that the burner may be withdrawn as soon as the root or stump body begins to burn well.

.y improved device enables a stump to be destroyed comparatively quickly and. very easily, Without the use of any dangerous explosive, While the construction of the same is such that it may be veasily manipulated and may be produced at small cost.

What I claim is The improved device for the purpose specified, comprising a tube for conducting the liquid fuel, the discharge end of the same being cut away on the upper side, a

Wick inserted in such end and projecting therefrom and being supported on the extended lower portlon of the tube, and a Wire guard. applied to and projecting'above such discharge portion, one end of the guard being secured to the extended lower portion of the tube and the other end attached to the body of the same, the intervening portions overlying the exposed portion of the Wick, substantially as described.
